What type of music do you like to play when you are gaming?
If it is my first play through on the campaign I go bare so I can experience the game as a whole. With my 360 linked to my pc it is easier to stream music right through the game without background score overlap in most games, but that also means no cut scene dialog audio in others which is odd.
I usually play 50 Cent's Get Rich or Die Trying when playing FPS but this weekend i played Halo 3 with the Tron Legacy OST and it was surreal, especially with a killer sound system or headset (I only have a Turtle Beach X4).
